18F-FDG PET/CT Imaging of Eosinophilic Granulomatosis With Polyangiitis

A 29-year-old woman presented with asthma, fever, generalized rash, and numbness in the ring and pinky fingers of her right hand. Laboratory studies showed significant increases in blood eosinophils, C-reactive protein, and IgE, but ANCA (antineutrophil cytoplasmic antibodies) were negative. The 18 F-FDG PET/CT suggests scattered, segmented FDG uptake around small and medium vessels throughout the body. After comprehensive analysis, the patient's final clinical diagnosis was eosinophilic granulomatous vasculitis.
